I want to make my penis bigger .plz tell me how n is that possible .

Penis: There is no substance that an adult male can ingest, apply or inject that will change the size if the flaccid penis. Save your money.

Not possible: A change in perception might be in order. You can grow to accept what your genetics gave you, and learn how to better enjoy it (either with partner or without). It isn't size that matters -- it's how you use it. Good luck to you.
